Problem with system memory after jailbreakme (?), checked cydia and system memory shows utilization of 87% on a 3gs ios4. Previously jb with blackrain - had installed a bunch of cydia apps like infolock, sbsettings, irealsms, etc...working great. Now after upgrading to ios4 and jb - cannot install the cydia apps without system crashing and going into safe mode...tried rebooting - no good. I checked with ifile to look at caches etc. - nothing unusual. Did the previous blackrain jb reduce available system memory? Checked the system memory on a jb ipad and it shows only 65% utilization. Any suggestions? Thanks
